The answer is 25. Below: three ways to calculate it, a mental shortcut, and the real-world contexts where this percentage shows up.
25% of 100 is 25.
25% is exactly one quarter, so 25% of 100 is one quarter of 100.
Divide the percent by 100 to convert it: 25 ÷ 100 = 0.25.
Multiply: 100 × 0.25 = 25.
25% means 25/100. So 25% of 100 is (25 × 100) ÷ 100.
Compute: 25 × 100 = 2500, then divide: 2500 ÷ 100 = 25.
For 25%, divide by 4. 100 ÷ 4 = 25. Faster than working with 0.25.
25% is exactly one quarter (1/4). Many mental shortcuts for 25% rely on dividing by 4 instead of multiplying by 0.25.
A quarter of 100 is 25. Use this for tips when service was poor (a quarter off the bill), or to find a quarter of total credit hours.
